tea spilled on computer.

December 2, 2012 at 22:03:52
Specs: Windows XP

tea was spilled on my computer by a friend. he did not remove battery. It did shut off. I pulled battery and let unit dry out. left battery out and unit unplugged. Once dry I plugged in unit with battery out. before hitting start button it starts flashing screen white off and on. It will not start up and fan does not come on. It does how ever flash the screen white on and off as well as flash the first 2 leds white back and forth. Is this a trouble shooting code? After some on line research i took unit apart and did not find any thing that really looked out of the normal. the unit is a toshiba L655-s5150

I think the board is fried.

You know the real meaning of peace only if you have been through the war.

The issue could just be the keyboard. You have nothing to lose so you can try washing the keyboard with distilled water after removal and dis-assembly. You must thoroughly dry it.

I assume you dis-assembled further than that already?

Stop trying to get the computer to work as is before you do fry something that isn't yet damaged.

Liquids spilled on circuit boards allow current to flow across gaps that it is not supposed to. Circuits that are designed to carry a signal of maybe a tenth of a volt or so, suddenly get say 5 volts or more can be fried in a very short time (milliseconds). It is not the water it self, but the dissolved minerals, sugar, salts, and other electrolytes that do the damage. These remain on the board when the water evaporates and continue to do their damage when the power is restored. For these reasons, the power needs to be removed immediately, and the surfaces need to be cleaned off. OtheHill recommends Distilled Water and careful drying, which should work well, except that you need to make sure that all of the water is dried, even under circuit components. I generally recommend a high quality rubbing alcohol (95%+ isopropel) for the cleaning since it displaces water and dries much faster at normal room temperature. All circuit boards (both sides), keyboard, and anything that may carry a current needs to be cleaned (if it is not too late already).

You have to be a little bit crazy to keep you from going insane.

Be sure the rubbing alcohol is pure. Many have oil in them.

Mmm presumably this "is" a laptop and you managed to get inside the case completely...

I have known of a laptop that was bathed in coffee, and another in tomato soup, and both lived to tell the tale - after a total strip down, wash in distiller water, then a spray over with Iso-propyl alcohol, then gently warm air blow dried.. Then left to dry a while in a warm area - away from drinks etc... And a close inspection of all areas to ensure nothing deposited still across tracks (sugary stuff typically) - using a magnifying lens... Any such stuff being carefully scratched away with small (plastic) screwdriver type item. One has to look/inspect very carefully... Also ensure all key systems are totally free in travel (up/down) when pressed. Often they can/will stitck due to deposits from the spillage... Key caps can all be removed and replaced, allowing all clearances to be properly inspected/cleaned... Sticking keys could be part of your problem at this stage; although I feel it may be serious than that...

And then again there were keyboards that simply did not survive coffee, or tea, or soup; only water... Sugary drinks are really bad news for keyboards etc..., and the innards of laptops...
